Scattering not only broadens the width of the optical transition between two levels but can enable optical gain and absorption to coexist — a fact that is unambiguously demonstrated by the ...

Nathan Jukam from the École Nomale Supérieure in France spoke to Nature Photonics about how his ... can amplify the THz pulses of a TDS system using gain switching. This work has the potential ...

Weight gain can be frustrating. Traditional methods often fail, but nature offers many options for effective management. Physical activity can result in weight reduction across the entire body ...
